Locating Gray Fuel Pump Wire?
I'm trying to find the gray wire that takes power to the fuel pump (I need to tie my new ECM into this). I pulled up the driver side door sill and found 4 wires - and none are gray. See picture. One is black, one is pink/purple, one is orange and the other is brown/tan-ish. Should the fuel pump wire be in this cluster, or could it possibly be routed down the passenger side?

Re: Locating Gray Fuel Pump Wire?
Well...that explains why I haven't been able to find the gray wire 
I assume the wire I want then is the one on the bottom in my picture, the one that is tan colored? Not near my car, but I'm pretty sure that it has a white tracer on it. This would be the wire to tie to the Fuel Pump Positive wire from my wiring harness, right?
